CTICasesMassive Pulmonary Embolism and Thrombus through PFO
Imaging findings
The patient presented with a massive pulmonary embolism and a large thrombus noted in the right atrium, which extended through a patent foramen ovale into the left atrium. The thrombus was likely secondary to a tumor in the patient's abdomen.
Key takeaways
Always maintain a high index of suspicion for embolic thrombus through a PFO in the setting of venous thromboembolism, particularly when an underlying abdominal or pelvic malignancy is present.
